Table 7-31 Inertia compensation parameters
The scaling to modify the acceleration feed forward to accommodate the system inertia may be calculated from
A
= Inertia compensation scaling
B
= Inertia of the system in kg m

C
= Rated motor torque in Nm
D
= Gear ratio numerator / Gear ratio denominator
E
= Radius of the sheave
A = 1000 x B x D / (C x E)
Inertia compensation is not active during an autotune.
7.17 Simulated encoder output
The
E300 Advanced Elevator
drive has a simulated encoder output available when operating in Closed loop operating modes, which is generated
from the drive’s main position feedback at a default ratio of 1:1. The simulated encoder output (AB only) as default is derived through hardware from
the main position feedback connected to the drive’s encoder interface. Simulated encoder output is not available in Open-Loop.
Table 7-32 Encoder output options
Encoder Simulation Status
(
C29
) will display the hardware simulated encoder output which is available based upon the main position feedback device
set-up on the drive.
The hardware simulated encoder output (AB only) from default is derived through hardware,
Encoder Simulation Mode
(

) = 0 with an update rate
of 250
μ
s. Additional modes of simulated encoder outputs are also available, for further details refer to the
E200 Design Guide
.

7.18 Advanced door opening
An advanced door opening output can be configured on the
E300 Advanced Elevator
drive. This feature provides an output to the Elevator controller
to open the elevator car doors at a defined speed prior to the elevator car reaching the floor level. This allows the Elevator travel times to be reduced.
The advanced door opening output is generated based upon a speed threshold and routed to a digital output to the Elevator controller.
The advanced door opening speed threshold is configured by the user in
Velocity Threshold 1
(
H13
). In addition there is also an invert for the output
and status bit.

Description
Inertia Compensation Enable
(
E10
)
Enables the inertia compensation torque offset to be applied.
Inertia Compensation Total Inertia
(
E15
)
The total inertia is used in combination with Inertia compensation reference acceleration to derive the
torque required for acceleration.
Torque Per Amp
(
E16
)
This is used to scale the acceleration torque into percentage of system rated torque
